In scientific terms, how is power related to work? a. power is the rate at which work is accomplished. b. power is the ability to do work. c. power is the force of work over a certain distance. d. power is the energy supplied in a force.

A. power is the rate at which work is accomplished.

If we look at the power equation: Power = energy ÷ time

we can see that energy ÷ time is a rate of work because the energy is a change in energy and a change in energy is equal to work.

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction
